Purpose of the work
The French database of building airtightness has been fed by measurements performed by qualified testers since 2006. The database is enlarged each year by more than 65,000 measurements since 2016, making the total number of measurements about 420,000 at the end of 2018. This work presents a statistical analyses of the French database of building airtightness.

As the AIVC was created in 1979, the 40^th anniversary of the AIVC was celebrated in October 2019 at the 40^th AIVC conference in Ghent. In the context of this celebration, it was decided to publish 2 overview publications:

The AIVC (Air Infiltration and Ventilation Centre), TightVent Europe (the building and ductwork airtightness platform) and venticool (the platform for resilient ventilative cooling have organised during the past 9 years 34 webinars around a wide range of topics. The main topics of the events held include:

In the Framework of the IEA EBC Annex68 Subtask 1 working subject, we aimed at defining an indoor air quality index for residential buildings based on long- and short-term exposure limit values. This paper compares 8 indoor air quality indices (IEI, LHVP, CLIM2000, BILGA, GAPI, IEI Taiwan, QUAD-BBC and DALY) by using the French IAQ Observatory database that includes pollutant concentration measurements performed in 567 dwellings between 2003 and 2005. This comparison allows to make a relevant analysis of each index and determines their pros and cons i.e.
